To ALL WHOM ir MAY ooNoERN;

Be it known that I7 JOHN SCANIAN, of Chicago, inthe countyo'f Cook, andState of Illinois, have invented a new and useful Improvement inFelt'vRootmg; and I do hereby declare and make known that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings and the letters and figures marked thereon,which form part of this specification.

To enable those skilled in the art to understand how to construct anduse my invention, I wili proceed to describe the same withparticularity, making reference in so doing to the aforesaid, drawings,in which- Figure 1 represents a. plan or top v iew of my invention asarranged in strips upon the roof, and

Figure 2 is a section oi` one of said strips, showing the differentlayers composing the.$21111,nd their arrangement with heb other iSimilar letters of reference in the different iigures of thedrawings'deno'te the same parts of my invention.

A represents di`erent layers of the rooting as arranged upon a roof; thematerial being manufactured in strips of any desired length, and appliedas shown, extending across the root' in a. manner corresponding with thearrangement of the layers of shingles upon a shingleid root'. Each layeror strip of the rooting is composed of three layers or thicknesses offelt, or its equivalent., prepared in the manner hereinafter described.The lower stratum consists of dry felt a, which is designed to lie uponthe roof-boards, and is used in e dry state, to prevent its adhering tothe boards, as, in case of adhesion, there would be great danger ofinjuring the roofing by the shrinking otV the roof-boards, which wouldcrack it and cause it to leak. The nextstratum b is composed of feltwhich 4has been thoroughly saturated in coal tar, or its equivalent, andafterwards coated with or passed through a. melted'watcr-proofcomposition. Upon this is'arranged another layer of felt, saturated withcoal tar, und these three layers, being substantially of the same width,are arranged as shown with lrespect to each other, so as to form' a thinedgeto the strip for convenience in overlapping one strip upon another.The three layers are then passed through between suitablepressingrollers, or other pressing apparatus, which press the wholecompactly and firmly together, forming rolls of any desired width -orlerfgth ready for transportation.

This rooting can be applied readily by any one, arranging the layers asshown and specified, and securing them to the roof in any suitablemanner. The ordinary gravel coat may be applied upon this roofing afterbeing laid upon `the roof, if desired. Y

Having described the construction of my invention, and the manner ofapplying the same, I will now specify what I claim, and desire to secureby Letters Patent:

I claim, as a. new article of manufacture, rooting'composed ot' twolayers of saturated felt and one layer of dry fait, arranged as and forthe purposes specified.

JOHN SCANLAN.
